RAILWAY CAE CONSTRUCTION Elmer Latshaw, Philadelphia, ILa., assignor to The J. G. Brill Company, Philadelphia, Pa., a corporation of Pennsylvania I Application December 3i), 1933, Serial No. 194,630 22 (Cl. 105 19'1)- This' invention relates generally to railway car A constructionand has particular reference to car body mounting means.

One object of this invention is the provision of a new and improved side bearing arrangement for railway car trucks.

VlAnother object of the present inventionv is the provision of elastic means acting in shear to resist movements of the bolster with relation to the truck.

Still another object of this invention is the provision of bolster mounting means so formed that when no load is applied to the car the bolster is supported by spring means and when load is applied to the car to an amount sumcient to compress the spring means the bolster is supported not only by the spring means but by elastic means such as rubber or the like acting in shear. A further object of this invention is the provision of a bolster mounting means for railway car trucks including elastic medium acting in shear and so arranged as to prevent frictional engagement of metal truck Another object of this invention is the provision oi' a bolster mounting means for railway car trucks which is easy and comparatively inexpensive to manufacture and which is strong and durable in operation. t

Other objects and advantages of this invention will be apparent from the following description taken in conjunction with the Aaccompanying drawings, in which Figure 1 is a side elevation of a part of a car truck showing the present invention applied thereto, certain parts being shown in section and other parts being broken away, the view being taken on the linev I-I Fig. 2, and said view having one of the retainers removed;

Fig. 2 is an end view of the construction shown in Fig. 1, certain parts being broken away to disclose other parts in section; and

Fig. 3 is a' top plan view oi the constructionv shown in Fig. l.

Referring now more particularly to the drawings, in which only those truck parts necessary to an understanding of the present invention are` form but in .the instance shown'comprises an inlverted channel which is supported from beneath by coil springs I2 arranged in spring pocket I4 secured as by fasteners I6 to the inner surfaceof the side frame'and to the transoms T through the 5 medium of gussets I5.

Secured to the upper surface of the end portion of the bolster by fasteners I8 is a side bearing housing indicated generally at B and comprising a base 28 and side walls 22, the latter being con- 10 nected, intermediate their ends, by braces 24 which support-a pin 26 on which is rotatably mounted a roller 28 with Whicha wear-plate 38 secured to the lower surface of a car body bolster indicated diagrammatically at 32 is adapted to 15 contact. As more clearly shown in Fig. 2 the upper edge portions of side walls 22 are outwardly bent to provide retaining flanges 34.

Arranged on opposite sides of the bolster I0 and connected to opposite side frames in any 20 suitable or desired manner are transoms indicated generally at T, angles in the instance shown, the horizontal anges 36 of which are oppositely extended and support retainers R. The retainers R are preferably yangle shaped with the horizontal 25 flanges 38 thereof secured to the horizontal anges 36 of transoms T by fasteners 40. As clearly shown-in the drawings the vertical legs or flanges 42 of retainers R parallel the side walls 22 of the side bearing housing in spaced relation. y

Interposed between the side walls 22 of the side so bearing housing and the vertical flanges 42 of retainers R are connecting elements indicated generally at E and comprising elastic material such as rubber or other resilient material faced on oppo- 35 site sides by metal plates 46and 48 which engage, r respectively, against side walls 22 of the side bearing housing and the vertical flanges 42 of retainers R. Inpracticesthe rubber 44 is preferably vulcanized to the

plates

46 and 48 and is held in 40 compression between the side bearing housing and the retainers R, the flanges 34 being fitted into' elongated notches formed in the upper end portions of the plates 46 to prevent movement of said plates relative to the side bearing housing. For -45 preventing movement of plates 48 relative to the retainers R, the latter are provided with lugs 49 which are arranged in slots or notches formed in opposite end portions' of the plates 48 as more clearly shown in Fig. 1. In said Fig. 1 it can be ii()v seen that the retainer R has been removed in order to show the plate 48 and the means for prel venting relative movement thereof.

In installing the'elastic elements E, the side Walls 22, elastic elements E and vertical 'anges 55 42.01' retainers R are first bolted togetherprior to the attachment of the retainers R to the transoms Vposed on the bolster.

T. To permit such. bolting alined openings 50 are provided as clearly shown in Fig. 2. Bolting as just described. places the rubber 44 under compression following which the retainers R are secured to the horizontal flanges 36 of transoms T by the before-mentioned fasteners 40, the rubber 44 obviously remaining in compression after the ner and which is flanged upwardly as at 56 to lie against the compression member 4 of the side frame,.suitable fasteners 58 connecting the gusset to said compression member as more clearly shown in Fig. 1.

From the above description it can be seen that normally the bolster i0 is supported by the coil springs l2. Upon increase in load such as to compress springs I2 it will be obvious that the bolster is supported not only by the springs I2 but by the rubber 44 acting in shear; the rubber, of course, serving to aid in taking up the load im- In service, these resilient elements function to afford easy and resilient operation of the bolster and, when a car rounds a curve, it will be obvious that this rubber 44 acts in horizontal shear to at least a limited extent. It will also be seen that the rubber 44 acts in shear to resist lateral and vertical movements of the bolster, and is subject to compression to absorb the shocks incident to sudden application of brakes or starting thercar from a state of rest,

thus functioning as a cushioning and dampening means to effect smoother operation of the car in service.
